Abstract

Biodiesel is produce by transesterification process using alcohol and the most alcohol used in biodiesel manufacturing is methanol. Methanol is made from non-renewable material. Whereas, ethanol made from renewable materials and the price of pure ethanol is expensive. So, research to produce biodiesel with low ethanol concentration was conducted. This research was aimed to know the mole ratio of oil toward ethanol and the best reaction time in this biodiesel production. The mole ratios of oil toward ethanol used were 1:12, 1:14, 1:16 and the time reactions were one, two, and three hours. This research was started by heating the oil to temperature 60oC, then adding ethanol solution and NaOH and being reacted into several variations of time. After that, the separating and washing process were executed. From the analysis result, the biodiesel produced is appropriate with the requirements of SNI 04-7182-2006.

Abstract

Vegetable oil is one of the alternative sources of raw material for fuel oil to produce biodiesel. The conversion reaction process requires the help of a catalyst to break down triglycerides into methyl esters. Therefore, this study aims to determine the performance of catalysts made from coconut shells to convert bulk oil into biodiesel. The catalyst performance is focused on biodiesel's yield parameters through the influence factor of catalyst weight, molar ratio, and %FAME. This research was conducted in three stages, namely (1) catalyst preparation, (2) application of catalyst performance through the conversion process of bulk oil into biodiesel, (3) washing of biodiesel. The first stage was catalyst preparation carried out by utilizing a coconut shell, which was first made into charcoal, then activated using H3PO4 then sulfonated with H2SO4. The second stage was the conversion process of bulk oil into biodiesel using coconut shell catalysts through a transesterification process using variations in the catalyst's weight to bulk oil (0.5; 1; 1.5; 2; and 2.5% wt/wt) and bulk oil molar:methanol ratio (1: 3; 1: 6; and 1: 9). The third stage was the process of washing biodiesel using HCl. Based on this study's results, the best catalyst weight was 2% wt/wt with a molar ratio of 1: 9 resulting in the highest yield of 89% and the FAME of 80.36%.

Abstract

The effluent discharged from the batik textile industry often contains azo compounds and organic contaminants. One method employed to address these pollutants is the Electrofenton (EF) technique. This study aims to assess the effectiveness of electrofenton in reducing both color content and COD (Chemical Oxygen Demand) in batik dyeing effluent. The Electrofenton process was conducted in batch mode, varying electrode distances at 4 cm and 6 cm, H2O2:FeSO4 molarity ratios of (10:0.05) and (10:0.1), and electric voltage strengths at 6 volts and 8 volts. The research revealed that employing an electric voltage of 8 volts, an electrode distance of 4 cm, a contact time of 120 minutes, and a Fenton dosage molarity of 10:0.05 M resulted in a remarkable removal efficiency of 97.8% with a final concentration of 103 mg/L for color content. Additionally, for COD, employing the same parameters led to a removal effectiveness of 90.1%, with a final concentration of 730 PtCo. The impact of Fenton dosage on COD removal was statistically analyzed using the t-test. The computed t-value of 3.444 surpassed the tabulated t-value of 2.776, indicating a significant influence of Fenton dosage on COD removal.
